Physical properties

Hardness: 7 (Mohs scale); Color: Light violet to lavender; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: Indistinct; Specific Gravity: 2.65

Formation & geological history

Formed in hydrothermal veins and within geodes in igneous environments; the violet color is caused by natural irradiation of trace iron impurities (Fe3+) in the quartz crystal lattice.

Uses & applications

Predominantly used as a gemstone in jewelry, for decorative carvings, and as a popular mineral specimen for collectors and holistic practices.

Geological facts

Amethyst's name comes from the ancient Greek 'amethystos', meaning 'not intoxicated', as it was believed to protect the wearer from drunkenness. In antiquity, it was considered one of the five cardinal gemstones alongside ruby and emerald.

Field identification & locations

Identify by its light purple hue and ability to scratch glass (hardness 7). Commonly found in Brazil, Uruguay, Madagascar, and Zambia. Collectors should look for crystalline points or hexagonal basal sections.
